摘要
介绍了3次试重法、时频分析法、影响系数法、改进影响系数法共4种水轮发电机组动平衡试验方法。通过比较、分析各种试验方法的优缺点,并结合各方法实际应用情况,指出目前时频分析法和影响系数法是主要的动平衡试验方法。低转速水轮发电机组采用时频分析法更加方便、快捷,高转速水轮发电机组和双面配重平衡试验时则推荐采用影响系数法。
Four hydropower generator unit dynamic balance test methods including 3 times weight test method,time-frequency analysis method, influence index method, and modified influence index method are introduced. By comparing and analyzing advantages and disadvantages of all test methods, and combining with actual application situations of all test methods, it is pointed out that time-frequency analysis method and influence index method are currently mainly used dynamic balance test methods. Time-frequency analysis method is convenient and fast for the low speed hydropower generator unit,and influence index method is recommended for the high speed hydropower generator unit and the double weight balance test.
